Definitions

  • This invention relates to a system for measuring relative displacements of a rotating shaft in a direction transverse to the axis of the shaft.
  • Displacements of a shaft axis occur at frequencies comparable to or greater than the frequency of rotation of the shaft in many machines and apparatus.
  • a shaft which supports a grinding wheel in a grinding machine is subject to such displacement both as a result of imbalance of the rotating masses and as a result of external forces applied to the grinding wheel when it engages a workpiece.
  • Line 25C is connected to one input of the OR circuit 22 so that in addition to the interrupt sent when the synchronising signal on line D is received, an interrupt is - 7 -
  • the disc 10 may be replaced by a drum with a reflective grating formed on its outer surface and the light sources and detectors outside the drum.
  • the drum could be transparent with the light sources on the inside and the detectors on the outside, or vice versa.
